The Lonely Planet says: Beautifully perched beneath the raw peaks of the Rif, Chefchaouen is one of the prettiest towns in Morocco, an artsy, blue-washed mountain village that feels like its own world. While tourism has definitely taken hold, the balance between ease and authenticity is just right. The old medina is a delight of Moroccan and Andalucian influence with red-tiled roofs, bright-blue buildings and narrow lanes converging on busy Plaza Uta el-Hammam and its restored kasbah. Long known to backpackers for the easy availability of kif (marijuana), the town has rapidly gentrified and offers a range of quality accommodation, good food, lots to do and no hassles to speak of, making it a strong alternative to a hectic multicity tour. This is a great place to relax, explore and take day trips to the cool green hills. Families take note.
Chefchaouen is split into an eastern half (the medina), and a western half (the ciudad nueva, or new city). The heart of the medina is Plaza Uta el-Hammam, with its unmistakable kasbah. The medina walls have recently been repaired, with Spanish funding. The principal route of the new city is Ave Hassan II, which stretches from Plaza Mohammed V, a leafy square designed by artist Joan Miró, past the western gate of Bab el-Ain, around the southern medina wall and into the medina itself. Here it dead-ends at Pl el-Majzen, the main drop-off point. The bus station is a steep 1.5km hike southwest of the town centre. The falls of Ras el-Maa lie just beyond the medina walls to the northeast.
